For those unfamiliar with the Aero line of mufflers, they are a compact stainless steel muffler designed to be added to nearly any exhaust system that offers unrestricted airflow, while having unremarkable sound characteristics. The XL line of the AeroTurbines are considered their resonated version designed specifically to cancel out any in-cab drone that is typical of many aftermarket mufflers.
Built from T304 stainless steel inside and out, this muffler does not have any of the traditional packing found in many other mufflers that is known to breakdown over time, but rather uses a series of louvered baffles that are also designed to literally "suck" the exhaust away from the engine, even faster than a straight pipe, which results in lower exhaust gas temperatures.

Straight Pipe to 4040XL
Bought this to help get rid of cab drone when driving the truck. Went from straight pipe from turbo to exhaust tip, to installing the 4040XL. This significantly reduced the raspy sound that the exhaust had, and made a much cleaner exhaust note. Drastically reduced the drone when under load at or near 2000 rpm. Install was fairly easy as existing exhaust had 6 1/2 years and 47,000 miles of use already. Installed with lap style clamps to make it a clean install. Would recommend the Aero exhaust lineup to anyone looking for a clean sound with little to no cab drone.

I put this on my 06 cummins 5.9l 6spd. i took the cat and factory muffler off and replaced it with this muffler. It is a great quality muffler and sounds amazing as a replacement for the factory muffler. No drone quiet while cruising and nice deep cummins growl when accelerating. Awesome product would definatley buy again.

Excellent finish, excellent product. On my 2012 Duramax it results in a very nice, deep mellow tone with zero drone at highway speeds.

I'm very happy with this muffler. It sounds great and installed easily on my 2007.5 6.7 cummins. The truck has all of the deletes and this was the last item it needed. Great customer service also!

This muffler sounds great on my 2003 6.0 powerstroke! I added this to my 4 turbo-back straight pipe system just behind the downpipe. Killed the vacuum cleaner sound at idle and much better turbo spool up with awesome tone!

Is this a slipp on and clamp over the four inch exhaust or a straight weld on muffler?
This will slip over 4"" exhaust, you may then clamp or weld it.

Where would be the proper position to install? front of exhaust, under cab, or just before the rear axle ??
That muffler is going to work best placed as far forward in the exhaust as possible.

I currently run a Gibson cat back setup on my 2005 5.9. The power gain is fine, but the drone is getting worse. Does the 4040XL have similar power gains and does anyone know if it is quieter than the Gibson setup? Also, are these legal in CA? Thanks!?
Not familiar with the Gibson system so I can't say if this would be louder then that muffler or not. It is typically a little quieter then a standard straight through performance muffler. The Aero muffler would flow just as well as a straight through muffler, you would see the same power gains there. The muffler alone should not have any issue being legal in CA on a Cat back system.-Sands
